and 6. Theoable-drum consists of the pulley 51, the peri hery-ofwhichis grooved to receive a cab e, and the journal 52 of which l I is extended at one side and turns upon the movable nut 56 screwed thereon. Byt-his meansg thetwo pulleys are held together adjustaibly and o ment. Each of flrQgulleysds also provided aperture 5 extending from the ed by a rounded depression 58.

As shown in Figffpthe cables; are'iwinpped in oppositedirections around I enables the cabledrum torun freely between t the two parts of the bracket, as will be read peripheries thereof by being passed through the aperture and knotted as just stated. The crank 50 is held in inoperative position in any suitable manner, as by a loop 59, secured to the side of the boat within the operative range of the handle. This prevents accidental movement. Viewing Fig. 7, it will be seen that the cable 60 is secured to the pulley 51, while the cable 61 is secured to the pulley 53, one at the top and the other at the bottom of the respective pulleys when set and held in normal position, such as shown in Figs. 5 and 7; The cable 60 is led through a series of loops 62 under the rail of the boat to a pulley 63, and from thence to a pulley 64, held by bracket 65, at an angle to the pulley 63, and thence is connected to the operating-handle of the detaching-gear, in this instance an offset handle such as 29, Fig. l. The cable 61 is passed through several guide-eyes 66, to the pulley 67, and thence to a pulley 68, both carried by a brace 69, or transverse bar of the boat specially provided therefor, and thence to the operating-handle of the sterndetaching gear, in this instance a straight handle 27, such as shown in Fig. 1. It will now be understood that the, boat to be launched will be suspended from the block-andfall or supporting-tackle by means of the hook, ring or other device 5, Fig. 1, and that, the strain upon the boat is egualized throughout its length by reason 0 such support at the opposite ends thereof. The said supporting means 5 is first inserted within the recess 5, then the holding-bar 12 is turned down to horizontal position, the locking-lever is then turned into the position of Fig. 1, the latch is then pushed into the position of Fig. 1 under the extension 16 of the locking-lever, the supporting-lever 33 is then pushed under the head of the weighted latch, and the lockingpin 38 is then inserted through the apertures 39, thus seating it in the groove 37 of the supporting-lever. The operating-handle 27 will naturally assume the position of Fig. 1, owing to its weight, and, if not, the movement of the supportingdever 33, operating through the. medium of its arm 34, upon the hook 23 of the tripping-dog, will force the latter downwardly and consequently the operating-handle 27, the two devices assuming the position of Fig. 1. When the boat is lowered into the water, or at an time during its descent toward the water, it can be released from the supporting-tackle simultaneously at both ends by manipulating the lever 50. Ordinarily, however, the boat will be loaded on shipboard and connected to the supporting-tackle of the davits as just described, whereupon the launching mechanism will swing the boat outboard to clear the ship and will then lower the boat into the water. The locking-pins may be removed just before the boat is moved outboard, or said locking-pins may not be released until the boat is about to reach the water. The sailor sitting near one end of the boat, or on the seat adjacent the operating-arm 50, will be in charge of the boat and will be on the watch to release the boat at the proper time. At the proper time, he will give the word to the men in the opposite ends of the boat to draw out the pins 38, thus enabling him by an upward movement of the lever 50 to exert a direct pull upon the operating-handles 27, 29, thus causing the trippingdog, through its cam-surface 22, operating upon the pin 21 of the latch, to throw the latter outwardly, thus releasing the locking-lever and enabling the strain upon the supporting tackle to immediately throw the holdingbar 12 into the position shown in Fig. 2. The boat is thus released and the sailors can at once dip their oars and row away.

From the foregoing it will be seen that it is impossible to release the boat from the launching apparatus until the pins 38 have been removed and that the strain of the boat upon the launching-tackle will prevent release. of the boat until a positive pull is made upon the operatingdiandles 27, 29. This positive pull is produced by operation of the lever 50, which turns the pulleys 51, 53, simultaneously in the same direction and draws the cables 60, 61, in opposite directions, thus tripping the handles 27, 29, in opposite directions. It will also be seen that the pull is direct upon the handles 27, 29, that the slack in the cables 60,61, can be taken up, so that the movement'thereof will be simultaneous and equal instantly upon manipulation of the lever 50, and that the boat thereby can be evenly and instantl released at both ends from the supporting-tackle of the launching mechamsm.

My detaching or releasing gear can be tripped automatically, if desired, this being accomplished by removing or leaving out the pins 38. lhe strain of the launching tackle upon the holding-bar 12 will cause the extension 16 of the locking-lever 10 to tightly grip the latch with immense pressure, the latch being held in the upright position of Fig. 1 against ordinary shocks or attempts to move the same. When, however, the boat reaches the water and the launching-tackle, through its hook or loop 5*, releases pressure upon the holding-bar '12, the tendency of the weighted head 18 of the latch will be to release the latter from the extension 16 of the locking-lever. Hence, lack of pressure on the locking-lever or a slight shock or jar of the boat, or of the releasing-gear, will cause the latch to shift from under the extension 16 of the lockinglever and thereby automatically release the loo boat or the gear from the launching-tackle. It -will be understood that this will occur when the boat is water-borne. Under this mode of operation, the operating-arm 27 is not manipulated and the tripping-dog has no function. The arm 34 of the support 33, howeverywill perform-its functions when the "latch engages the same, as before described. The automatic release of the boat, as just described, can be accomplished either when the bdat is loaded. or When it is empty but this mode "of'releasing the boat from the laiinching tackle Will usually be employed when it'isdesired to drop the 'empty'boat into thewater and allow it to trail by its connection with the painter to the loop or hook 13.

Having'thus described my invention, what I claim and desire to secure by Letters Patent is: I
